Abstract: A method of performing a percutaneous multi-probe treatment includes: acquiring a scan image of an object to be treated with multi-probe percutaneous insertions; determining a first point in a region of interest (ROI) in the scan image; determining a second point at a surface of the object in the scan image; generating a reference trajectory by connecting the first point and the second point; arranging, around the first point, a number of third points corresponding to tips of probes to be inserted into the object; generating planned insertion trajectories for the probes based on the number of probes to be inserted and the reference trajectory; and causing a monitor to display superposed on the scan image, at least one of the planned insertion trajectories. The planned insertion trajectories extend in a geometric relationship to the reference trajectory and pass through the third points and through one or more second points.
